	True
	False

Answer 1

1) The product of complete combustion are Carbon Dioxide and Water.    (TRUE)

2) H₂ + CH₂=CH-CH₃ ----> CH₃CH₂CH₃.                            (ADDITION)

*Also called catalytic hydrogenation.

3) Hydrogenation of unsaturated vegetable oils raises the melting point and makes them more solid.       (TRUE)

*Hydrogenation increases the hydrocarbon content increasing the melting point.

4) Hydrogenation is used to convert alkenes and alkynes to alkanes.               (FALSE)

*Hydrogenation is used to convert alkyne to alkene/alkane.
